A long cable with cylindrical cross section has inner conductor of radius a and an outer conductor of inner radius b and outer radius c. The dielectric constant of the material between the conductors is 3. The potential on the inner conductor is VO and the potential on the outer conductor is 0.a)solve Laplace's equation in the dielectric region between the inner and outer conductors to find the potential V(r) in the region a <= r <= b.b)Find the formula for the electric field intensity E in the region a <= r <= b.c)Find the magnitude of the electric field intensity on the inner conductor surface if VO = 10 volts, a = 1mm, b = 5mm, and c = 6mm.
Add Z1 = 3ej30 degree and Z2 = 4e -j60 degree together. Write your result in both rectangular and polar form. In polar form, indicate whether your angle is in radians or degree s. Multiply Z1 = -2 + j3 and Z2 = 4 + j2 together.
A charge density is uniformly distibuted over a linear section from 0
Suppose that you wish to offer a voice over IP wireless service. The target packet error rate (or drop rate) is 10^3 and you determine that if the signal is confined to within a coherence band, about 20% of the packets are dropped due to fading.
Suppose you have a need for a D type flip-flop, but only have access to T type flip-flops. Implement a circuit equivalent to a D-type flip-flop with a t-type flip-flop and some extra logic gates.
In a typical AC circuit, the supply voltage is 10 VPK and frequency is 60 Hz. If the current through the system is 2 APK with a phase angle of 60o, then the power dissipated by the source is
constructed using standard value resistors a. Without making a single calculation, which resistive element will have the most voltage across it Which will have the least b. Which resistor will have the most impact on the total resistance.
Research about origin, formation process, and age of oil. What type of biota contributed to oil formation How is that linked to marine environment being conducive to oil formation What are the prospects for offshore oil beds
a) What would be the value of the parity bits. b) If some of the bits get flipped in transmission and the following bits are received 1101 0101 0001 0010 1010 with the parity bits, can you detect the error. Can you correct it.
Once the voltage across the load reaches 5V the load will no longer act as an open circuit and the capacitor will discharge. Once the load voltage has droped to 0.2 the load will act as an open circuit and the capactior will begin to charge once ..
Design a first-order digital highpass chebyshev filter (.5-db ripple) with a cutoff frequency of 850 Hz and a sampling frequency of 10 kHz. Determine the transfer function using BLT.
The first stage is a transconductance amplifier with an input resistance of 2k ohms, an output resistance of 100k and a gm=0.002A/V. The second stage is a voltage amplifier with an input resistance of 5k, an output resistance of 18 ohms and a volt..
